Description
To learn an object's center of gravity and how it can be changed.

Objectives
Students will:
• Investigate the concept of center of gravity.
• Determine the center of gravity of a two-dimensional object by balancing it on the top of a pencil.
• Change the center of gravity of a two-dimensional object by adding paper clips and balancing it on the top of a pencil.
